Usage

Deploy to Kubernetes Cluster

Different cluster environments can set different kubeconfig files for the --kube.kubeconfig parameter. Currently, Docker images are used, and private registries can be configured.

go run main.go kube --default.appdir=~/workspace/hellogo --docker.username=qiuguobin --docker.password=*** --kube.kubeconfig=~/Downloads/config -e TZ=Asia/Shanghai

go run main.go kube --default.appdir=~/workspace/hellojava --docker.username=qiuguobin --docker.password=*** --kube.kubeconfig=~/Downloads/config -e TZ=Asia/Shanghai

go run main.go kube --default.appdir=~/workspace/hellonode --docker.username=qiuguobin --docker.password=*** --kube.kubeconfig=~/Downloads/config -e TZ=Asia/Shanghai

Deploy to VM Cluster

Install Ansible. Different cluster environments can set different host lists for the --ansible.hosts parameter, separated by commas.

go run main.go vm --default.appdir=~/workspace/hellogo --ssh.username=guobin --ssh.password=111111 --ansible.become_password=111111 --ansible.hosts=192.168.1.9 --ansible.role=go

go run main.go vm --default.appdir=~/workspace/hellojava --ssh.username=guobin --ssh.password=111111 --ansible.become_password=111111 --ansible.hosts=192.168.1.9 --ansible.role=java

go run main.go vm --default.appdir=~/workspace/hellonode --ssh.username=guobin --ssh.password=111111 --ansible.become_password=111111 --ansible.hosts=192.168.1.9 --ansible.role=nodejs
